Write an equation in slope-intercept, point-slope, or standard form for the line with the given information. Explain why you chose the form you used.
a. passes through (-1, 4) and (-5, 2
b. slope 2, y-intercept -4
c. has an x-intercept of 6 and a y-intercept of 3
d. passes through (1, 2) with slope -5/3

well we have different forms of equation of a st.line :
===============================
>> if you are given two points then it will be in the form \[\frac{ y-y1 }{ y2-y1 } = \frac{ x-x1 }{x2-x1 }\] where the two points are (x1,y1) ^ (x2,y2)
>> if you are given the slope and the y-intercept
\[y=mx+c\]
where m is the slope and c is the y-intercept
>> if you are given a point and the slope
\[y-y1=m(x-x1)\]
>> AM NOT SURE OF THIS I guess if you are given y-intercept and x-intercept so implicitly we are given two points we can consider it like the case of two given points
I recommend you check the last one cuz am not certain about it
